Centrifuge modeling of geotextile-reinforced soil retaining walls

Article Abstract:

The results obtained by A. Porbaha and D.J. Goodings on their centrifuge experimental study on geotextile-reinforced cohesive soil retaining walls are compared with theoretical data in terms of the limit-equilibrium technique. Using this approach, the lower- and upper-bound estimates for the geotextile strength from the wide-width and zero-span tests are calculated. The equations derived from this technique and their application to centrifuge modeling are discussed.

Seismic rehabilitation of earth dams

Article Abstract:

The seismic rehabilitation of earth dams is investigated. More research is required on residual strength, which is considered as the main factor when planning magnitude and cost rehabilitation. Computer programs are recommended for estimating deformations, but users should be cautious when designing rehabilitation strategies due to the lack of field experience to confirm predictions.
